IMPROVED WINDOW-SASH ADJUSTER.

Specification forming part of Letters Patent No. 34,967, dated April 15,1362.

T0 all whom it may concern:

Be itknown that I, GEORGE JONES, of Peeks* kill,in the State of NewYork,liave invented a new and useful Machine for Moving and AdjustingVVindow-Sash in the Frame; and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the accompanyingdrawings, makingpart of this specification, and to the letters of reference markedthereon.

Figure l of the accompanying drawings rcpresents the sash and frame asthey appear to the eye, in which only the lower ends of the rods b b andthelower rests or supports of the rods a a arc visible. Fig. 2 is avertical section of the sash and frame, in Which- A represents the sash,in the sides of which are grooves B B. In these grooves the rods b b arefastened by means of the rests or sup port-s a a and ff to the trame,and to the sash A are fitted the gages h 71 made of any suitable metal,and to these gages are attached the curved metallic springs t' il, whichact at both ends on the rods Z1 b and hold the sash A steadily to therods l) h, and while allowing the sash to move freely and easily up anddown retain it steadily and iirmly at any point or place at which thehand moving the same may be withdrawn.

Fig. 2 represents the upper sash. The lower sash is moved up and down inthe same way by similar rods, springs, gages, &c., constructed in likemanuel', the sash always remaining stationary whenever and wherever thehand moving it is withdrawn. The rod has been used for a similar purposebefore; but the curved metallic spring attached to a gage fastened tothe sash and working at the ends on the rod, as above described, is theoriginal invention of the undersigned.

My window-adjuster is simple of construction, easy of action, saveslabor and material in making window-frames, is very durable, not easilyput out of repair, and when needing repairis easily got at for thatpurpose. It Works without noise, and requires but little force to workit with ease. It also saves time in being applied to new buildings, andmay be used in old ones as a substitute for the weights and pulleys orother apparatus. It may be applied to windows of all sizes, and is veryuseful, steadying the window.

That I claim as my invention, and desire to secure by Letters Patent,is`

The combined application of the curved metallic spring, rod,and gage,constructed in grooves in the sides of the window-sash, to the movingand adjusting of the sash within the `frame, by means of which both theupper and lower sash may be moved up and down Witnesses:
